Configuring BGP Filtering with Route Maps

Within BGP, route maps can control and modify routing information and t define the conditions by which
routes are redistributed between routing domains. See the
Information" section on page 39-99
that identifies the it (map tag) and an optional sequence number.
Beginning in privileged EXEC mode, follow these steps to use a route map to disable next-hop
processing:
Command
Step 1 configure terminal
Step 2 route-map map-tag [[permit | deny] |
sequence-number]]
Step 3 set ip next-hop ip-address [...ip-address]
[peer-address]
Step 4 end
Step 5
show route-map [map-name]
Step 6
copy running-config startup-config
Use the no route-map map-tag command to delete the route map. Use the no set ip next-hop ip-address
command to re-enable next-hop processing.

Purpose
(Optional) Change the default local-preference value. The
range is 0 to 4294967295; the default value is 100. The
highest local-preference value is preferred.
(Optional) Configure the number of paths to be added to
the IP routing table. The default is to only enter the best
path in the routing table. The range is from 1 to 16. Having
multiple paths allows load-balancing among the paths.
(Although the switch software allows a maximum of
32 equal-cost routes, the switch hardware never uses more
than 16 paths per route.)
Return to privileged EXEC mode.
Verify the reset by reviewing routing table information
and BGP neighbor information.
(Optional) Save your entries in the configuration file.

Purpose
Enter global configuration mode.
Create a route map, and enter route-map configuration mode.
(Optional) Set a route map to disable next-hop processing
• In an inbound route map, set the next hop of matching routes as
the neighbor peering address, overriding third-party next hops.
In an outbound route map of a BGP peer, set the next hop to the
•
peering address of the local router, disabling the next-hop
calculation.
Return to privileged EXEC mode.
Display all route maps configured or only the one specified to verify
configuration.
(Optional) Save your entries in the configuration file.
